Transmission of IP over Ethernet over IEEE 802.16 Networks
Abstract
This document describes the transmission of IPv4 over Ethernet, as
well as IPv6 over Ethernet, in an access network deploying the IEEE
802.16 cellular radio transmission technology. The Ethernet on top
of IEEE 802.16 is realized by bridging connections that IEEE 802.16
provides between a base station and its associated subscriber
stations. Due to the resource constraints of radio transmission
systems and the limitations of the IEEE 802.16 Media Access Control
(MAC) functionality for the realization of an Ethernet, the
transmission of IP over Ethernet over IEEE 802.16 may considerably
benefit by adding IP-specific support functions in the Ethernet over
IEEE 802.16 while maintaining full compatibility with standard IP
over Ethernet behavior.
